1)please i want to apply the cec_funct in GSA istead the function Z in the file finess. Number of these functions I mean the CEC_func(30 functions) 

so you can apply one by one or you can apply all in the same time 

I will send you file how to aplly these functions 

2) please there are many hybrid algorithms used for optimization such as (hybrid pso- gsa) and (hybrid bpa- gsa). For my case I want tp hybrid (BHA-GSA)for optimization,and use the same application(cec_func) so what is the problem? 

please see the atach file( i need like this ) it is so easy.
